Mellow Mushroom Cottleville - The Story

Inspired by the aesthetic of the 1980’s, our restaurant celebrates all things Cottleville and Missouri. The 80’s inspiration started with the Delorean, a vehicle that the owner Tammi Hilton’s father drove for many years, because of this, there is a large mural of a Delorean with a license plate reading “88 MPH”. Eye-catching exterior murals were painted by local artists Daniel Burnette and Peat “The Eyez Guy” Wollager. The colorful interior murals were created by artist Ruben Ubiera.
